Wed Jun 19 01:27:57 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>

	* math/Makefile (distribute): Add ieee-math.c.

Wed Jun 19 03:24:58 1996  Ulrich Drepper  <drepper@cygnus.com>

	* locale/codeset_name.c: New file.  Provide function for information
 	about currently used character set.
	* locale/Makefile (routines): Add codeset_name.
	* locale/langinfo.h (_NL_CTYPE_CODESET_NAME): Add new constant.
	* locale/localeinfo.h: Change magic number because of incompatible
	change.
	* locale/C-ctype.c: Add initializer for new field `codeset_name'.
	* locale/programs/ld-ctype.c: Implement handling of `codeset_name'.

	* locale/programs/locfile.c: Don't depend in pre-2.0 Linux specific
 	name `MAX_IOVEC'.  Instead use standard name `UIO_MAXIOV'.

	* locale/setlocale.c (setlocale): Initialize local variables to
	prevent warnings.
